Due to the small flying heights typical of air bearings, external gas pressure sources must be free of contaminants in order to allow proper operation.

Incoming air/gas should be conditioned to the following:

Absolute filtration of particles to 1 microns

Relative humidity less than 85% (non-condensing)

No oils/ resins/ wax (coalescing / charcoal filter)

System designs should include provisions to prevent accidental motion of the bearing without adequate pressure.    Pressure Interlocks and/or locking mechanisms with hardstops are prudent additions to mechanisms which use air bearings.  Please contact us for more information.
